摘　　要：对折流杆换热器在壳程不同结构参数和不同工况下的平均角度场进行了数值计算,结果表明:折流栅间距对平均角度场的影响较小、折流栅有效流通面积即折流栅的最大流通面积与壳程截面积之比对平均角度场影响较大。而Re数对平均角度场影响也较大。Computed the average angle field according to the rod baffle heat exchanger structural parameter change. The results show the distance of rod baffle is a little influence for the average angle field in the shell side of heat exchanger. Whereas the ratio between the fluid area and the cross section area is bigger influence for the average angle field in the shell side of heat exchanger. So does the dimensionless number Re.
